I also suggest an adjustable ring compressor. They come in a set from Snap-On (Blue Point?) with a ratchet to hold the compressor ring closed.
Oil everything well and hit the piston with a purpose that the piston rings have no time to expand the very moment when they slide in.
The ratchet registers offset on the ring compressor. Place the lower end towards the bore and square the ring when you hit home.
If you have studs on the rods, sleeve with fuel hose that they won’t nick the journals.
No
oil between the bearing halves and the rod/main.
There are a 100+ more engine building tips, but I guess you did your research :-)
Merry Christmas!
